The Substitute

Jonathan Shale (Tom Berenger) is a Vietnam vet and mercenary. His mission to destroy a Cuban drug facility fails and his crew is disavowed. He returns to Miami where his girlfriend Jane Hetzko teaches history in a rough school. She confronts a gang led by student Juan Lacas (Marc Anthony). She's attacked by a big Seminole and rescued by Shale. Shale goes undercover as substitute teacher James Smith. Claude Rolle (Ernie Hudson) is the corrupt principal.

This is another one from the genre of white teacher saves gang-ridden school. The difference here is that the teacher is freaking Rambo. The violence is dialed up to body-count territories. It can't be taken seriously. It also can't be completely taken as action fun. Some may see this as camp. I see this as something that struggles in between.
